What is linearity?
Principle that asserts that a specific sound in a word corresponds to a specific phoneme.
What is segmentation?
Principle based on the notion that the speech signal can be divided into discrete units that correpsond to specific phonemes
What is Speaker Normalization?
How listeners are able to recognize sounds and words despite the large variations in the way that speakers produce them
What is the basic unit of perception?
-varies by listening situation and age
-infants use larger units, like syllables
-process at smaller levels as lexicon increases
What is the Serial-order Issue?
Issue of which elements of speech are serialized: vocing, nasality, phonemes, syllables, etc.
-phoneme/syllable sized unit favored by current research
What are Degrees of Freedom?
different options of muscle contractions to make different formations within the oral, pharyngeal, or laryngeal cavities
active vs passive theories of speech perception
Active: stress links between speech perception and speech production

Passive: emphasize sensory aspects of speech perception
Bottom-up vs Top-down theories of speech perception
B-U: based on premise that all information necessary for recognizing sounds is contained in acoustic signal--no need to involve cognition in processing sounds

T-D: emphasize higher-level linguistic and cognitive operations in analysis of sounds

Target Model of speech production
-goal is acousitc output
-helps acount for coarticulation and talker variability (rate, stress
Feedback Model of speech perception
-auditory output serves as feedback for info ragarding how we move articulators thru proprioceptive, kinesthetic, and tactile manners
Feed Forward Model
-signals make adjustements at periphery to prive for efficient, coordinated system
-faster process than waiting for feedback
-may help explain why disruptions don't really affect speech production
Dynamic systems model
-provide explanation that would reduce degrees of freedom
-proposed that groups of muscles link together to perform tasks
-synergy, coordinated structure formed to achieve goals
Connectivist Model
-nodes which have a presence of absence of a feature to define a target word
Motor theory
-active theory
-individual perceives sound becaus s/he produces it
-listener's experience with producing speech gives awareness of relationship between artic/vocal tract/acoustic consequences
Acoustic invariance theory
-each phoneme has it's own corrosponding set of acoustic features
-"core of characteristics" acts as template that listener compares to incoming sounds
Direct realism model
-speech perception does not rely on specialized and unique processes
-process analagous to vision
-objects/events percieved directly
-interactive activation: dynamic informaion processing system, extitatory and inhibitory interactions among processing units (phonemes, features, words)
-connectivist model, parallel processing of multiple sources of information
Logogen Theory
-word is detected, logogen activation level raised
-when level raised high enough, logogon threshold of recognition is crossed and word is recognized
Cohort Theory
-Autonomous stage: acoustic-phonetic info at begining of input word in memory have same word-initial information
-> info comprise 'cohort'
-when cohort activated, inappropriate words deactivated
Fuzzy Logical Model of Perception
-3 operations in phoneme indentification
-features evaluated to determine presence in an interval of sound
-features assignes continuous fuzzy values (def. absent -> def. present)
-prototype matching
Native Language Magnet Theory
-phonetic categories of language are organized in terms of prototypes
-perceptual protopytes serve as speech production targets for infants and children, providing link between perception and production
